"They were ordering them to get me thrown out, saying, 'Throw him out of here, throw him out of here. Beat the hell out of him.'" Ken Hamidi said.

However, union leaders told a different version of what happened.

"He came to a union meeting with another woman who had film equipment. He was asked to leave," Yvonne Walker, President of SEIU Local 1000, said. "When he refused, he became abusive to members of our staff. He actually physically assaulted a couple of our staff people."

Shortly after the incident, Hamidi was taken to a local hospital for treatment of cuts to his head and face.

Hamidi is an outspoken critic of the union. He hosts a cable access show that regularly criticizes leaders of SEIU.

Hamidi admits that police have escorted him out of previous union meetings.

It's unclear if any criminal charges will be filed.

"The statements we received kind of conflict about who started it and who provoked it," Sacramento police Sgt. Norm Leong said.

Both sides said they want to press charges and are hopeful that the district attorney will determine who started the fight.
